The best air filter depends on the size, filtration rating and quality. Mobley Heating and Air offers the highest performing, most affordable filters on the market.
Replacing your air filters is as easy as finding the right size, opening your intake vent, removing the dirty filter, and placing the new filter snugly in its slot. Be sure not to bend or crease the new filter to get maximum performance.
It is recommended to replace your air filter every 90 days or 3 months.
MERV - Minimum Efficiency Reporting Value is a rating which determines how much your air filter is capable of. Most air filters have a MERV rating from 1 to 20. MERV 1 removes large particles or debris whereas MERV 20 is capable of filtering microscopic particles such as viruses and bacteria from the air. Mobley Heating and Air offers MERV 8, MERV 11 and MERV 13 ratings.
All filters have a nominal size and an actual size. The nominal size is rounded up to the nearest whole or half inch and printed in a larger font. The actual size is an exact physical measurement of the filter, printed in smaller font.
